Issue with RoadRunner and Koala

I have Ubuntu Karmic Koala on my laptop. For some reason my wireless card has been on the lam. I am trying to get some reading done for school and at the same time it is time for an update on Ubuntu, my only issue is getting an internet connection.

I have roadrunner internet connection and Karmic Koala. I am a complete n00b when it comes to this stuff. If anyone can help me with getting the laptop to recognize Roadrunner when it is plugged in it would be great!
